We know that specific frequencies excel at detecting certain species of fish:
Bluefin Tuna—60 kHz, squid—133 kHz, and cod—175 kHz. The PM265LH transducer
includes all these frequencies plus every other frequency in the high and low
bandwidths. This powerhouse delivers excellent resolution, bottom
discrimination, and bait and game-fish separation at all depths.
Airmar’s PM265LH is packed with a seven-element, low-frequency array that
operates between 42 and 65 kHz for excellent deep-water performance. The
high-frequency ceramic operates between 130 and 210 kHz with a narrow, 10° to 6°
beam—perfect for picking apart structure and pinpointing tight-holding fish in
structure
